چکیده انگلیسی

ObjectiveTo observe reinforcing effect of calcium sulfate cement (CSC) bovine bone morphogenetic protein (bBMP) on vertebral in the rabbit model of osteoporosis.MethodsA total of 48 New Zealand white rabbits were randomly divided into group I (blank control group), group II (CSC injection group), group III (CSC/bBMP injection group) and control group. White rabbit osteoporosis model was established rapidly by using castration method+methylprednisolone candidate. After modeling, groups II, III were given corresponding vertebral body injection material, and 4 animals were sacrificed respectively at 24 h, 6 weeks, 12 weeks after vertebral plasty. Tissue pathological status, vertebral mineral density and vertebral body bone mechanical strength were observed.ResultsVertebral body structure form was normal in the groups II and III. Trabecular bone coarsens, connection and repair were observed in micro fracture and bone defects, bone trabecular connectivity was superior to group I significantly; vertebral body compression strength in the groupI was on the decline, vertebral compression strength in the groups IIand III was on the rise, the largest vertebra. Postoperative BMC and BMD in groups IIand III were incresed, and significantly higher than group I after 6 weeks (P<0.05), BMC and BMD in group III after 12 weeks were higher than the other three groups.ConclusionCompound bBMP CSC has good bone induction. It can improve the three-dimensional construction effect for osteoporosis vertebral trabecula, and can significantly improve the vertebral strength, as a vertebral packing material with good application prospect.
